+ link errors.
+
+ And, because we want to turn the common code into a library, this
+ file can't live there.
+
+ So, it lives in gdb and is built separately by gdb and gdbserver.
+ Please be aware of this when modifying it.
+
+ This also explains why this file includes common-defs.h and not
+ defs.h or server.h -- we'd prefer to avoid depending on the
+ GDBSERVER define when possible, and for this file it seemed
+ simple to do so. */
